|Space Time Gravitation - Yu. Vladimirov, N. Mitskievich, J. Horsky|
An historical survey of our ideas about space, time and gravitation. In three chapters, the authors consider how space and time were perceived from ancient times to the present (as marked by the publication of Einsteinâs theory of relativity) how they are now perceived, and finally how this field of mathematics and physics might develop in the future. Although there are many presentations of our current understanding of this subject on the market, the topics covered in the second chapter of the...

|MIT 8.224 Exploring Black Holes: General Relativity & Astrophysics, Spring 2003 - MIT OpenCourseWare|
Study of physical effects in the vicinity of a black hole as a basis for understanding general relativity, astrophysics, and elements of cosmology. Extension to current developments in theory and observation. Energy and momentum in flat spacetime; the metric; curvature of spacetime near rotating and nonrotating centers of attraction; trajectories and orbits of particles and light; elementary models of the Cosmos...
